Since it is a week end, I thought I would share this non technical stuff
with you:

In a far away land rich with natural resources, there is a big bank with
branches all over the country.

They have many databases taking care of their every day business needs.
Databases/applications are well implemented to the satisfaction of
users. They work properly and give the desired output.
Most things are automated: backup processes, cron jobs automate many
other things. An operator takes care of changing the tapes. The DBA
does not have much to do. The bank has lots of money. They even change
the disks once a while, not waiting for the MTBF. Apparently, no
modification was needed in the production system.

For several years nothing goes wrong with the database. DBA leaves to
pursue other opportunities. The management decides not to replace the
production DBA. They do not see the need for replacing the DBA. (I dont
know about patches and upgrades, restores and other things... ) After
all nothing went wrong in the years when the DBA was there. (It seems
there was only one DBA).

But it so happened after the DBA left, one fine morning, a main mission
critical application dies, because of some problem (later they came to
know because of some database issue). That day business in all the
branches of the bank all through the country had to be conducted with
papers, transactions recorded in papers.
